I'm hunting for the best solution on how to handle keeping large sets of DB records "sorted" in a performant manner.

Problem Description

Most of us have work on projects at some point where we have needed to have ordered lists of objects. Whether it be a to-do list sorted by priority, or a list of documents that a user can sort in whatever order they want.

A traditional approach for this on a Rails project is to use something like the acts_as_list gem, or something similar. These systems typically add some sort of "postion" or "sort order" column to each record, which is then used when querying out the records in a traditional order by position SQL query.

This approach seems to work fine for smaller datasets, but can be hard to manage on large data sets with hundreds (or thousands) of records needing to be sorted. Changing the sort position of even a single object will require updating every single record in the database that is in the same sort group. This requires potentially thousands of wri

In early November, 2012, Apple issued a graphics update for all mid-2012 MacBooks. In a continued streak of stupidity, however, this update forces your Mac to use "Safe Sleep". This means that the entire contents of your RAM is written to your disk every time you put your Mac to sleep.

This is retarded on the scale of the Titanic's navigational plan for two reasons:

1) Your Mac likely has 8 or 16GB of RAM. This is a ton of wasted disk space; especially on MacBook Airs that ship with only 256GB SSDs to begin with.

2) SSDs wear out as you write to them. Each cell of a SSD can only be written to a certain number of times before it becomes read-only. If you put your computer to sleep many times a day, OS X is slowly but surely destroying your SSD with unneeded write cycles.

Worst of all, the graphics update makes it IMPOSSIBLE to turn off safe sleep using the standard approach you'll find on Google:
